9 Claims. (Cl. 101-1) This invention relates to a tool for use with indexing means of-the kind employed on printing or printing and control devices or the like for the purpose of imparting particularity thereto.

Printing devices of the kind disclosed in Gollwitzer Reissue Patent No. Re. 22,249, patented January 12, 1943, or Hueber Patent No. 2,425,323, patented August 12, 1947, or printing and control devices of the kind disclosed in Gollwitzer Patent No. 2,132,412, patented October 28, 193 8; customarily have associated therewith so-called indexing means in the form of detachable tabs that are adapted to extend beyond an edge of such a device, each such tab including a portion that is secured in retaining means in the form of a socket provided in the body of the carrier of the printing device adjacent to the edge thereof beyond which a portion of the tab is adapted to extend. Printing and printing and control devices of the aforesaid character are passed through machines equipped with sensing means adapted to cooperate with the tabs and which regulate the operation of operative elements in the machine in accordance with the particularities of the printing devices that are imparted thereto by the selected positions of the tabs thereon. It is essential that indexing means of this nature be firmly retained in position so as to insure against displacement thereof in the course of passage of the devices through machines of the aforesaid character or in othenhandling thereof, and resultantly resort has been advantageously had to an index tab of the kind disclosed in Gollwitzer Patent No. 2,049,439, patented August 4, 1936. A tab of this kind includes a body portion that is adapted to extend beyond the edge of the printing or printing and control device to which it is attached, and the tab also includes a stem portion extended from one edge of the body portion and which is adapted to be inserted selectively into retaining means, commonly referred to as sockets, provided in the body of the carrier of the printing or printing and control device, retaining means of this nature being disclosed in the patent to Gollwitzer No. 2,049,436, patented August 4, 1936, such retaining means being particularly adapted for cooperation with tabs of the kind disclosed in aforesaid Patent No. 2,049,439.

The stem portion of a tab of the aforesaid character includes a yieldable tongue that is normally disposed in die plane of the stem but which is so arranged that when the stem portion of the tab is inserted into a socket of the kind disclosed in aforesaid Patent No. 2,049,436, camming means, that are a part of the socket, act on such a tongue to force the same out of the plane of the stem to thereby bring the free end portion of the tongue into position to engage an edge of a panel that is a part of the socket arrangement, such end of the tongue engaging such edge of the panel when the stem portion of the tab is fully inserted into the socket therefor. This is effective to prevent displacement'of the tab from the socket unless and until the yieldable tongue is depressed to disengage the free end thereof from the aforesaid edge of the panel.

2,855,843 Patented Oct. 14, 1958 When, however, the tongue is so depressed the tab may be freely withdrawn from the socket, but until the tongue is so depressed the tongue remains in retaining position and the tab is firmly held in the desired position on the printing or printing and control or like device.

The yieldable tongues that are provided on the stems of tabs on indexing means of the aforesaid character are necessarily of restricted size, and while such tongues may be depressed by engaging a fingernail therewith, it is advantageous to provide manipulative means for depressing the tongue. The manipulative means that have been proposed heretofore have been relatively expensive and it is therefore the primary object of this invention to provide manipulative means in the form of a tool that will be relatively inexpensive but which will, nevertheless, be eifective, upon proper manipulation thereof, to depress a yieldable tongue of the aforesaid nature so as to facilitate detachment of the tab of which the tongue is a part from the retaining means in which it has been secured.

Printing and printing and control devices of the aforesaid nature are of predetermined and uniform size, especially insofar as particular styles thereof may be concerned, this being necessitated by the design of elements in the machines through which the devices are passed that are to cooperate with the devices in the course of passage thereof through the machines. It is, therefore, another important object of this invention to provide manipulative means in the form of a detachment tool of such nature that a device of the aforesaid character may be inserted thereinto in such a way as to facilitate proper orientation of means on the tool with the depressible tongue of a tab mounted on the device so that depression of the tongue will be effected upon subsequent manipulation of the tool, and an object related to the foregoing is to so arrange a tool of the aforesaid character that it will embody means of the aforesaid character that will cooperate with the yieldable tongue of a tab in at least selected ones of the various positions at which a tab may be mounted on a printing or printing and control device or the like.

Other and more specific objects of this invention are to form a tool of the aforesaid character from relatively rigid but yieldable material; to so form the tool that insertion of a printing or printing and control device thereinto may be expeditiously efliected; to so arrange the tool that indicia may be provided thereon which will facilitate identification of the positions on a printing or printing and I control device whereat indexing means in the form of a tab of the aforesaid means may be selectively secured, and to provide a novel tool of the aforesaid character that will be of simple and economical construction and yet eflicient and positive in operation.

Other and further objects of the present invention will be apparent from the following description and claims and are illustrated in the accompanying drawing which, by way of illustration, shows a preferred embodiment of the present invention and the principle thereof and what I now consider to be the best mode in which I have contemplated applying that principle. Other embodiments of the invention embodying the same or equivalent principle may be used and structural changes may be made as desired by those skilled in the art without det 3 W fig. 4 is a fragmentary horizontal sectional view showing the manner in which the tool is arranged to cooperate with yieldable tongues on indexing means secured at er us qs qns a one an e of a printing or p n ns andcontroldegicq and which view is taken substantially along the line L4 on Fig. 5;

In the accompaj'yin"drawing a printing and control device D of the aforesaid nature is illustrated which in; chides a carrier the end portions of which are folded u eataeiasivesfts provide spacing flanges as SF which pi c'tjbey nd the rear faceof the carrier C and which se e to space the devices one from the other in the drawers or the like in which such devices are customaristored when not in use and on which the devices travel g co'ur'se of passage thereof through the machine. Retaining lips as RL are struck up from the face of the carrier C and cooperate with a bead UB formed along the upper edge or the carrier to retain a card as CA orifthe earner C along 'the upper edge thereof. Other retaining devices RLP cooperate With ahead LB formed along 'the lower edge of the carrier C to retain a printing plate I on the face of the carrier C. Type characters (not shown) are customarily embossed on the plate P to have impressions made therefrom when a printing device D including "such a plate is passed through a suitable printing machine. Customarily an impression from at least selected ones of such type characters is made on a c rd "as "CA to facilitate identification of the printing device D of which such a plate and a card are elements. The "strafed described printingdevice is illus- V V f 'a widevariety of "such devices which, as is well unders ol 'inth'e art, may have one or more cards as CA seetrreathe eon and which may also carry one or more printing plates as P.

Along what is customarily referred to as the upper edge of the carrier C, a plurality of "sockets generally indicated by S are provided. Each of these sockets includes a panel PA that is offset from 'the body of the carrier Con "the rear face thereof and which desirably is arranged in parallel relation with the body of the carrier Inwardly'of each panel PA,"each'so'cke't includes an inclined panel IPA which is offset from the body of the carrier "C onthe rear face thereof but which is arranged in inclined relation with the body of the carrier to'defiiie an opening 0 aligned with the passage between the panel PA and the body 'of the carrier C. Desir'ably a'plur'alit'yof sockets as S are provided on each carrier C and customarily twelve such sockets are provided so that a fab as T may be'mounted'in any one or more of. twelve positions along an edge of a printing or printing and *control device as D.

'Each 'tab as T includes a substantially rectangular body p'ortion of which the greater portion is adapted to extend beyond the edge of a carrier C when a tab is secured in 'a socket as S, such extension of a portion of the body of a tab being shown in Fig. 2. Each tab as T also includes a stem portion as ST which is narrower than the narrowest dimension of the rectangular body portion of the tab and which projects from one of the narrower edges of the body of the tab. Each stem portion is equipped with a yieldable tongue as YT that normally lies in the plane of the stern ST. When, however, the stem portion ST of the tab as T is inserted into a socket as S, the leading edge of the stern portion ST first passes under the panel PA and then enters the opening 0 and moves along the inner inclined face of the panel IPA so that when the tab is properly inserted in the socket, as shown in Fig. 5, the free end portion of the stem ST is inclined out of the normal plane thereof. Such inclination of this "end portion of the stern of the tab and the edge E of the opening 0 is effective to cam the yieldable tongue YT out of the plane of the stem ST, and when the tab is fully inserted the free edge of this yieldable tongue is disposed behind the lower edge of the panel PA with which it cooperates to prevent withdrawal or accidental displacement of the tab T from the socket S in which it is so mounted. in order to remove a tab as T from a socket as S it is necessary to so depress the yieldable tongue as YT that the free edge thereof is moved out of alignment with the lower edge of the panel PA and when this is done the tab may be withdrawn and immediately after slight outward movement of the tab T from a socket S the tongue as YT may ride along on the inner surface ofthe panel PA and, when the tab is fully withdrawn from the socket, all parts thereof are free to resume their normal positions.

As can be ascertained by reference to Fig. 2, the yieldable magmas as YT are of restricted size, and it is therefore advantageous to provide manipulative means to facilitate depression thereof to enable withdrawal of a tab as T from a socket as S, and the detaching tool of the present invention is arranged to facilitate such depression of a yieldable tongue as YT.

While the tool of the present invention may be made from a wide variety of materials, I prefer to form the same from a thermoplasti material such as a celluloseacetate, polystyrene or kindred synthetic resinous material for so to do imparts the desired resiliency to the tool and-enables the same to be of relatively light weight and otherwise facilitates handling thereof. The toolis formed by folding a substantially rectangular sheet of thermoplastic material or the like upon itself toprovide substantial parallel 'butspaced-apart walls as it and 11 intereonnected by a substantially U-shaped bight portion 12 Desirably, the wall 19 is'of greater extent than the wall 11 and the wall '11 is desirably slightly inclined toward the wall-10 but remains spaced therefrom whereby a space or pocket is afforded into which a printing or printing control or like device may be inserted. "In order to facilitate such insertion of such a device, a flange 13 is afiorded along the free edge of the wall 11 and the flange 13 is inclined away from the wall lltl so as to thereby afford a relatively wire throat leading to the pocket into which a device as D is to be inserted.

As best shown in Figs. 1 and 7, the upper portions of the side edges of the walls 10 and 11 are slightly inclined inwardly so that the portions 14 and 1-5 of the side edges of the walls adjacent to the bight portion 12 are straight. As best shown in Fig. 7, the edges 14 and 15 of the walls of the tool are spaced one from the other in such a degree as to enable the portions 14 and 15 to he neatly fitted between the inwardly disposed faces of the spacing flanges as SF provided on a printing or printing control or like device asD. As stated hereinabove, such devices are of uniform size, especial-1y insofar as particular styles maybe concerned, and it will be understood that the'space between edges as 14 and 15 will be related to the space afiorded between the inner surface of spacing flanges as SF on the particular device with which my novel 1061 is who employed. Hence, when a device as D is inserted intothe pocket between the walls '10 and 11, the edges inwardly of the wall.

, be freely withdrawn from the socket.

twelve tab sockets are provided 14 and 15 cooperate with adjacent faces of the spacing flanges as SF on the inserted device as D to prevent endwise displacement of the device from the tool and this also facilitates proper orientation of the device in the tool, as will be explained.

In the portion of the wall 10, extended beyond the flange 13 and adjacent to the upper free edge of this wall, one or more protuberances as 16 are formed to extend Where a device as D with which my novel tool is adapted to be used includes twelve sockets as S, it is advantageous to provide a corresponding number of protuberances 16. Furthermore, the pro tuberances as 16 are aligned one with the other across the wall as 10. Yet further, the protuberances as 16 are spaced from the bight portion 12 to such an extent that when the lower edge of a device as D, with which my novel tool is designed to be used, is inserted between the walls and 11 and engaged with the inner surface of the bight 12, the projections as 16 will be respectively aligned with the sockets S and also in alignment with the yieldable tongue as Y T on tabs as T selectively inserted into the sockets as S on the particular device. Therefore, when a device as D has been inserted between the walls 10 and 11 and the lower edge thereof engages the inner surface ofthe bight portion as 12 and the edges 14 and 15 on the tool respectively cooperate with the adjacent faces of the spacing flanges SF on the device, the assembled elements may -be grasped in the hand, as shown in Fig. 8, and by applying pressure to the outer face of the wall 10 adjacent to aparticular protuberance 16, such protuberance may be forced down into engagement with the underlying yieldable tongue YT which, upon the application of sufiicient pressure, will be bent toward the body of the carrier C so that the free end of this particular tongue will be moved out of alignment with the inner edge of the panel PA of the socket S in which the particular tab is inserted and thereupon the tab as T may Upon release of the pressure effective to so depress a yieldable tongue as YT, the printing device D may be freely withdrawn from my novel tool.

It has been explained that the devices as D customarily have twelve sockets as S provided therein so as to thereby afford accommodation for twelve tabs as T. Thus, one or more tabs as Tmay be selectively secured in the sockets as S in the printing device as D for the purpose of imparting particularity thereto, which is to say, for the purpose of classifying the device and when the entire exposed portion'of a tab as T is utilized for this purpose, twelve primary classifications are afforded.

However, by cutting away a portion of the exposed portion of each tab sothat one-half of each tab may afford a primary selection, the number of primary selections that is afforded is increased to twenty-four where as is explained in Duncan Patent No. 1,082,505, patented December 30, 1913. Furthermore, by providing an embossure at any one of four different positions on the exposed portion of a tab, in an instance where twelve sockets are provided, it is possible to afford forty-eight primary selections, an arrangement of this character being disclosed in the patent to Gollwitzer 1,930,799, patented October 17, 1933.

In the patent to Hueber No. 2,359,851, patented October 10, 1944, a printing machine is-disclosed which embodies what is called a selector arrangement that is adapted to cooperate with indexing or classifying means in the form of tabs on printing devices for the purpose of 1 controlling the functioning of operative elements in the machine. I This patent discloses a selector which may be arranged to cooperate with tabs arranged to afford twelve, twenty-four or forty-eight primary selections, as described hereinabove, and this patent also discloses an arrangement wherein by selectively forming a perforation at one of five different positions in the exposed portion of a tab,

any instance where twelve tab sockets are provided, the: number of primary selections may be increased to sixty- It is also explained in the aforesaid Patent No. 2,359,851,

that whether resort is to be had to an arrangement affording twelve, twenty-four, forty-eight and sixty primary selections, that by disposing properly arranged tabs in various of the sockets a wide subordinate classifications may be afforded.

It has been customary heretofore to number the positions at which'tabs may be selectively attached to a device as D so as to thereby facilitate insertion of the tabs in position to afford a particular primary or subordinate classification as may be desired. Heretofore, this has; been done by engraving or otherwise forming numerals on the rear face of the carrier C of a device as D but because of the relatively limited area on the particular device where such numerals could be afforded in association with, the sockets to indicate the primary selecting positions, it. has sometimes been somewhat difiicult to read the nurn-j of the arrangements of the exposed portion of a tab as T that have been explained hereinabove.

Thus, it has been explained that each protuberance as 16 is arranged for alignment with a tab receiving socket as S on a particular device as D with which the tool is to be used. Consequently, by scoring or imprinting thev exposed face of the wall 10 panels as 17 may be defined thereon. Numerical indica as 18 may then be provided,

in each panel 17 to indicate the numbers of the positions at which primary selections can be afforded by inserting a tab into the socket as S on the device as D aligned with a particular protuberance and the panel associated therewith when a device as D is inserted into the novel tool of the present invention in a manner described hereinabove.

Thus, byreferring to Fig. 1, it will be noted that the numerals 1 to 12 are respectively afforded in the panels 17 associated with the respective protuberance as 16,-

engraved or imprinted at an appro-i such numerals being priate position in the panel. These numerals 1 to 12 serve to numerically designate the twelve primary selections that may be afforded when resort is had to full tabs as T for the purpose of imparting particularity to.

a device as D to classify the same.

Since resort may be had to cut away tabs such as aredisclosed in aforesaid Patent No. 1,082,505, which are so-called half-tabs, and which afford twenty-four primary selections where twelve tab sockets are provided. The numerals 13 to 24 are provided in the aforesaid panels respectively in association with the numerals 1 to 12..

This numerical indicia may be afforded on the wall 10 in the same manner as that described hereinabove and this numerical indicia identifies the twenty-four positions at which so-called half-tabs may be selectively mounted to afford any one of the twenty-four primary selections afforded by such tabs.

The numerals 25 to 36 are also afforded in the panels,

17 respectively in the panels bearing the numerals 1 to 12 and this likewise applies to the numerals By'referring to the right-hand most panel 11, shown in Figs. 1 and 4, it will be noted that the numerals 1, 13, 25,

and 37 are inscribed in the panel in such positions as to be indicative of the four positions at which embossures or openings may be formed on the exposed body of a tab 7 as shown in aforesaid Patent No. 1,930,799. Moreover, the numerals 49 to spective panels 17 at what may be called a middle posivariety of secondary or:

60 are suitably afforded in the reexposed portion of a tab be afforded toimpa'rt a beprovided thereon in sufficient' size as to enable facile reading'thereof and this ofcourse expedites the attach.- men't' of indexing orclassification means to devices" as: D.

lt will bemanifest from-the foregoing description that I have provideda noveltool which may be employed in alignin indexing: means such as tabs on printing, printingcon't'rol or; like devices. Where such indexing: means include yieldable tongues operative to effectively retain the indexing means onthe device, my novel tool may be employed to expeditiously retract such tongues from retaining position whereby removalv of the indexing means from: the device is facilitated.v It will, therefore, be apparent that I have:- provided a tool' which enables the hereinabove set forth and: kindred objects of. this; invention to' be realized;
